Important Question And Answer: Civil - Quality Control and Safety during Construction

Civil - Construction Planning And Scheduling - Quality Control and Safety during Construction


1.       Define by Sampling by variables.

          Instead of using defective or non defective classifications for an item, a quantitative quality

          measure or the value of a measured variable is used as a quality indicator. This testing procedure is

          referred to as sampling by variables.

2.       Define by Sampling by attributes.

          The  acceptance  and  rejection  of  a  lot  is  based  on  the  number  of  defective or a non

          defective item in the sample. This is referred to as sampling by attribute.

3.       Define injury frequency rate.

          It is defined as the number of disabling injuries per 1,000,000 man-hrs worked. A

          disabling  injury  is  an  injury  which  causes  a  loss  of  working  time beyond the day,

          shift or turn during which the injury was received.

          Injury frequency rate = number of disabling injuries x 1,000,000

          Number of man-hrs worked

4.       Define injury index.

          It gives the overall picture of injuries signifying both frequency and the severity

          and it is expressed by the equation,

          Injury - index = Frequency rate x Severity rate

          1000

5.       What are the types of statistical sampling in quality control?

          The types of statistical sampling in quality control are,

1)      Sampling by attributes

2)      Sampling by variables

 

6.       What are the standards measured in safety construction?

Provide Helmets for workers Requiring Eye Protection Requiring Hearing Protection Supply Safety Shoes Provide First Aid facility

 

7.       What are the various temporary Safeguards in construction?

Guy lines Barricades Braces Railings Toe Boards

 

8.     How do you improve the job site in construction?

Design

Choice of technology

 

Educating workers Pre-qualification of contractors

 

9.     How do you improve in total control?

1) To improve worker enthusiasm

2) To reduce the defective items

3) To increase the cost of items

4) To insure safe and effective construction

 

10.        What are the materials Specifications available in construction?

1) The American Society for Testing and materials (ASTM)

2) The American National Standards Institute (ANSI)

3) Construction Specification Institute (CSI)

4) American  Welding Society (AWS)

 

11.        What are the factors affecting Quality in construction?

1)  Incorrect Design

2)  Improper workmanship

3)  Lack of attention in worksite

4) Lack of training in construction work

 

12.    Define Quality.

Quality is defined as the fitness for the purpose and it satisfies the customer.

 

13.    Mention the causes of Accident in a construction industry.

1) Physical Accident

2) Physiological Accident

3) Psychological Accident

 

14.        What are the functions of Inspection?

1) Material Inspection

2) Process Inspection

3) Equipment Inspection

4) Finished Job Inspection

15.        What are the Various Safety equipments?

 

Helmet Gloves Shoes Goggles Safety Belts

 

16.        Mention two safeties Quotation.

Make safety a habit Good work is a Safe work

 

17.        What are the technical services required for inspection?

1) Engineers/Designers/Architect/Geologists

2) Supervisors

3) Scientists

4) Technicians

5) Field Laboratory

 

6)  Base Laboratory

7) Equipment testing and repair unit

 

18.Define safety.

 

Safety is hardly a procedure or a programme. It is a way of life, a state of mind, a force of habit and it must be part of each individual, in every activity, at all times and everywhere.

 

19.Mention the Physical causes of Accident in a construction industry.

Accidents caused due to Machines Accidents caused due to tools Accidents caused due to materials Accidents caused due to uniform Accidents caused in working environment

 

20.     Define injury -severity rate.

It is defined as the number of days of lost time because of injuries per

 

1000 man-hrs worked. The injury - severity rate which indicates the severity of injuries, is expressed by the equation,

Injurity - Severity rate = number of days lost x 1000 Number of man-hrs worked
